Ladies and Gentlemen:

                  We have acted as United  States  tax  counsel  for  Pengrowth
Energy  Trust (the  "Trust") in  connection  with the filing of a  registration
statement on Form F-3 (the  "Registration  Statement")  with the Securities and
Exchange Commission (the "Commission")  pursuant to the Securities Act of 1933,
as amended (the  "Securities  Act"),  and the rules and regulations  thereunder
(the "Rules"), in respect of 5,000,000 trust units (the "Trust Units") issuable
pursuant to the Trust's Distribution Reinvestment Plan (the "Plan").

                  We have been  asked to render our  opinion as to certain  tax
matters in connection with the Registration  Statement.  Capitalized terms used
but not defined  herein have the  respective  meanings  ascribed to them in the
Registration Statement.

                  In  rendering  our  opinion,  we have  examined  originals or
copies,  certified  or  otherwise  identified  to  our  satisfaction,  of  such
agreements and other  documents as we have deemed relevant and necessary and we
have made such  investigations of law as we have deemed  appropriate as a basis
for the opinion expressed below. In our examination,  we have assumed,  without
independent verification,  (i) the authenticity of original documents, (ii) the
accuracy of copies and the genuineness of signatures,  (iii) that the execution
and delivery by each party to a document and the  performance  by such party of
its obligations  thereunder have been authorized by all necessary  measures and
do not  violate  or  result  in a  breach  of or  default  under  such  party's
certificate  or instrument of

formation and by-laws or the laws of such party's jurisdiction of organization,
(iv) that each agreement  represents the entire  agreement  between the parties
with  respect  to the  subject  matter  thereof,  (v) that the  parties to each
agreement  have  complied,  and  will  comply,  with  all of  their  respective
covenants,  agreements  and  undertakings  contained  therein and (vi) that the
transactions  provided  for by each  agreement  were and will be carried out in
accordance  with  their  terms.  In  rendering  our  opinion  we  have  made no
independent  investigation  of the facts referred to herein and have relied for
the purpose of rendering this opinion exclusively on those facts that have been
provided  to us by you and your  agents,  which we assume  have been,  and will
continue to be, true.

                  The opinion set forth below is based on the Internal  Revenue
Code of 1986, as amended,  administrative rulings, judicial decisions, treasury
regulations  and  other  applicable  authorities,  all as in effect on the date
hereof. The statutory provisions,  regulations,  and interpretations upon which
our  opinion is based are  subject  to change,  and such  changes  could  apply
retroactively.  Any  change in law or the  facts  regarding  the  Plan,  or any
inaccuracy  in the facts or  assumptions  on which we relied,  could affect the
continuing validity of the opinion set forth below. We assume no responsibility
to inform you of any such  changes or  inaccuracy  that may occur or come to an
attention.

                  Based upon and subject to the  foregoing,  and subject to the
qualifications  set forth herein, we are of the opinion that the statements set
forth under the caption  "United States Federal Income Tax  Considerations"  in
the Registration  Statement are an accurate  general  description of the United
States federal income consequences  described therein.  Such statements do not,
however,  purport to discuss all United States federal income  consequences  of
the  ownership  and  disposition  of the Trust  Units and are  limited to those
United States federal income  consequences  specifically  discussed therein and
subject to the qualifications set forth therein.

                  We are  furnishing  this  letter  in our  capacity  as United
States tax  counsel to the Trust.  This  letter is not to be used,  circulated,
quoted or  otherwise  referred  to for any other  purpose,  except as set forth
below.

                  We hereby consent to the filing of this opinion as an exhibit
to the Registration Statement, or in any amendment thereto pursuant to Rule 462
under the  Securities  Act, and to the reference to us under the heading "Legal
Matters" in the prospectus  included in the Registration  Statement,  or in any
amendment thereto pursuant to Rule 462 under the Securities Act. In giving this
consent,  we do not agree that we come  within the  category  of persons  whose
consent is required by the Securities Act or the Rules.
